Specifications
Accuracy
Accuracy is specified for a period of one year after calibration, at 18 °C to 28 °C (64 °F
to 82 °F), with relative humidity to 90 %. Accuracy specifications are given as:
± ( [ % of reading ] + [ number of least significant digits ] )
AC mV, AC V, AC µA, AC mA, and AC A specifications are ac-coupled, true rms and are
valid from 5 % of range to 100 % of range. AC crest factor can be up to 3.0 at full-scale, 6.0
at half-scale, except the 3000 mV and 1000 V ranges where it is 1.5 at full scale, 3.0 at half-
scale.
